WHAT IT DOES

What verifyIdentityWithId does on Fusionauth

AI agents use verifyIdentityWithId to create or update resources in Fusionauth, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Fusionauth environment.

RISK

Why verifyIdentityWithId is rated Medium

Verifying a user identity is a write operation that modifies the verified state of a user account. It is reversible (verification can be revoked) and does not execute code, delete data, or involve financial transactions. Misuse could allow unauthorized accounts to gain verified status, hence medium severity.

RECOMMENDED RULE

The rule that runs verifyIdentityWithId safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Fusionauth, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For verifyIdentityWithId, this is the rule to start with:

verifyIdentityWithId Rate-limited

verifyIdentityWithId stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
